RAIL ANCHOR.

Application filed July 19, 1924. Serial No; 726,995.

To all whom it may concern v Be it known that'I, PERRY H. HAMILTON,

a citizen of theUnited States, residing at Mount \Vashingtomin the State of Maryland, have invented certain new'and useful .sln'iprovements in Rail Anchors, of which the following is a specification. v My-invention relates to rail anchors of the type comprising a clip adapted to be applied to the base flange of a rail from one side thereof, and when in position adapted by engagement with some fixed portionfof thetrack to hold the railfrom creeping longitudinally. J i. Itis the object of my invention to provide a new and improved combination of parts by which such a clip can babe utilized to advantage for the purpose specified, and also to provide an improved form of clip.

The preferred means by which I have accomplished my several objects are illustrated in the drawin and are hereinafter specifically describe That which I believe to be.

new and desire to cover by Letters Patent is set forth in the claims.

In the drawing,

F 'g. 1 is a. transverse sectional view. through a rail, partly broken away, being 1bstantially a section taken on line 11 of ig. 2 is ,a top plan view of the partsshown in Fig. 1. 1 1 Referring to the drawing,10 indicates a rail, supported bya cross tie 11, with a tie plate 12 interposed between the tie and the rail. Mounted on the flange of the rail at one side thereof, there is a clip 13, preferably 1 formed of high-grade steel, with its end portions normally spaced apart a distance less than the thickness of the rail base at the points engaged by said end portions, whereby said end portions are spread apart when the clip is driven into position upon the flange.v The clip'13 is made of'a bar of such cross-sectional size, and the shape'anddimensions of the clip are such that when the.

clip is 'driven'into operative position, as

shown in Fig. 1, theclip has a.very strong spring grip on the rail so as to prevent move- I ment of the clip" longitudinally of the rail.

In the construction illustrated, the 'tie plate is utilized forholding the 011 against movement with respect to the cross tae longi- I' tudinally of the track, andalso forholding the clip against backing 'transversely'from the flange of the rail. As is best shown in Fig. 1, the tie plate is provided with a slot '14 extending transversely of the rail and ofsuch dimensions and so' positioned that the outer face 15 of the slot engages" the outer face of the-clip, serving to hold the'clip in. position. 'lhe tie plate 12 is preferably provided with a rib or shoulder 16 adapted to engage the side face of the flange of the rail at the opposite side. The clip is thus effectively licldfagainst withdrawal from. the flange. At the same time theclip is held against movement with respectv to the tie longitudinally of the track by reason of the engagement of the .clip with the side faces of.

position upon the flange with the plate 12 I removed. Afterthe clip' has assumed its operative position, the pplate ,12 is then so I slipped between the rail and the cross tie, I

it being necessary, of course, that the rail and tie be separated sufiiciently for provid- I ing clearance for the plate below the clip until the plate can be brought into positionfor permitting the clip to enter the slot 14. The rail' and cross tie. are then permitted to assume their normal distance apart with the rail supported from the tie by the plate 12, j

in which position the clip is held against removal.

While I prefer to employ the construction as "illustrated-in the drawing, inwhich the longitudinally extending face or shoulder by which the clip is held in position is provided .in the form of the outer face'of a slot in a tie plate, it will be understood thatI do not desire to limit myself to this. particular construction except so faras the same is specifically covered by the claims, since it is evident that changes may well be made in the detailed form of the device without de-' parting from the spirit of my invention.

I claim: 1 v 1;"A rail anchor comprising a clip formed from a metal bar bent upon itself to provide spaced portions adapted to be driven. into ipping engagement with the upper and ower surfaces of the base flange ofa rail at one side of the rail, and a plate interposed between the rail and the cross tie and pro; vided with a slot extending transversely of the rail; for the reception of the lower end" portion of the clip, the arrangement being such that the clip'has a substantially s'nu fit in the slot longitudinally of the rail an that the outer face of the'slot is adapted by engagement with the outer face of the clip to hold the clip in its operative gripping' position on said flange. t

2.' A, rail anchor comprising acllp' formed from a metal bar bent upon itselfto provide spaced end portions having fiat bearingsurfaces adapted to be driven into gripping engagement with the upper and lower surfaces of the base flange of a rail'at one side of the rail, and a plate interposed between the rail and the cross tie'and provided with a slot extending transversely of the rail for the reception of the lower end portion of the clip, the arrangement being such that'the outer'endof the slot engages the outerfaee time clip m hold the clip in'its operative position on the flange.

A rail anchor comprising afclip formed from a metal bar bent upon itself to provide engagement with said surfaces and into engagement with the longitudinal edge of said base, and a plate interposed between the rail and the cross tie and provided with a slot extending transversely of the rail for the reception of the lower end of the -clip, thearrangement'bei-ng such that the clip bears against the side faces of said slot so as to portions which embrace the upper and lower surfaces of a rail base at one side thereof and adapted-to be driven into resilientgrippingbe held in a position substantially at right
